AdBlue in the Diesel Tank in Mumbles Hill? Keep It Switched Off
AdBlue in the diesel tank? Then keep your motor off — and your ignition as well. AdBlue is urea mixed in water. As it is water-based, it will not ignite and won't blend with diesel; trouble only comes when your pump begins drawing it. If the engine has not run yet, AdBlue in a diesel tank is usually emptied and carefully flushed where your car sits around Mumbles Hill. Before anything, phone us on 0333 366 0103.
Those opening minutes: AdBlue in the diesel tank around Mumbles Hill
Do these:
- Remove your keys, which stops someone turning the electrics on.
- Close to moving traffic? Then put your hazards on.
- Hold on to the till receipt or the empty bottle, and so you can tell us what went in and roughly how much.
- The van finds you fastest with a postcode starting SA3 4, or simply the name of a street nearby, so call from the car.
Things not to do:
- No starting the motor — not briefly, not to reposition the vehicle.
- Your ignition stays off: on many diesels, turning it on is enough to start the pump.
- Adding extra diesel does not help: AdBlue separates out rather than thinning.
- Never drive the vehicle anywhere, not even a short stretch along Mumbles Road.
- No draining it yourself, either, on the verge.
At a forecourt around Mumbles Hill, whether it is the Newton Garage or another one, ask the staff to help you push the vehicle clear of the petrol pump. On that drive, the car remains exactly where it was left.
What does AdBlue do in a diesel tank?
The motor is not what AdBlue is made for; your exhaust is. Its own tank holds it, and from there it's fed into your exhaust, and there it treats the fumes. Nothing inside an injection pump is made for this fluid — and no part of that was intended to travel through one.
It doesn't blend. After it's tipped into the tank, AdBlue acts not at all like diesel. The pickup takes fuel from the deepest part of the tank, and that's just where AdBlue settles: as it is heavier than diesel, it sinks. Simplest of all: a vehicle that got AdBlue in Mumbles overnight and hasn't turned since. The liquid waits at the base of that tank, untouched — but it would be first through if your engine starts, before any diesel at all.
It does two kinds of damage from there. What is left when the water evaporates is urea, which forms crystals: they lodge in tiny channels and clog filters. Worse, it eats at some metals in the fuel system, and keeps going till it's flushed out. By daybreak, a vehicle parked in Mumbles Hill with AdBlue in its lines grows worse; if it's only inside the tank, it doesn't. Diesel protects the injection pump and every injector as it flows; water gives none of that, which is a separate kind of harm.
Why AdBlue in a diesel is commonly more significant than petrol
Top up a diesel with petrol by mistake over at the Texaco, and this issue is diluted fuel. It mixes with your diesel, and whilst it is inside the tank it does no damage; the damage comes from running the engine on it.
AdBlue in a diesel is a fault of the wrong substance altogether. Not burning, it cannot just be run through. Nor can it be watered down, because it splits back out — and the following fill will not rinse away deposits or corrosion. So the flush matters more with AdBlue, and turning the key "to see", in the centre of Mumbles Hill or out in Oystermouth, does more harm than nearly any other error.
As with petrol, there is good news. Wherever in Swansea your vehicle has stopped, an unstarted engine means the AdBlue yet in the tank: the easiest part of any fuel system to clear.
How AdBlue ends up in a diesel tank in Mumbles Hill
In dim light, two caps together — the AdBlue one and the diesel one, occasionally behind a single flap — can look the same. Nobody means it; many layouts allow it. It mostly takes place at home, from a container bought en route home, rather than at the filling station.
It tends to take place in a few familiar ways. A warning light comes on during the school run, and the top-up takes place in a hurry outside the local primary school. In the evening, a container goes in on a driveway close to Limeslade Drive. Or a driver unfamiliar with that flap refills your car after dark, stopped in the car park outside The Pilot.
The least familiar cars see it the most — rentals, new ones, fleet cars, and the spare car in a family with one of each fuels. Same slip, an identical first response — keep it switched off — anywhere you are around Mumbles Hill or the rest of Swansea.
AdBlue in the diesel tank in Mumbles Hill, and the engine started?
If so, the AdBlue is no longer inside the tank. With any running, it travels to the injection pump and every injector, after passing through your filter and lines.
You may notice the engine running unevenly, smoking, losing power, showing warning lights or cutting out, maybe on the way back from Mumbles Hill Nature Reserve or halfway across Mumbles Hill. Once you safely can, pull over and switch it off — without restarting to test. With each start, more of it is pulled through.
Mumbles Hill sits under 10 miles from the M4; if you were on it, leave at the next junction and stop somewhere safe instead of driving on.
Every mile carries the AdBlue further into your system. That's why a hop across Mumbles Hill to park beside Limeslade Beach and a drive of under 5 miles towards Swansea are very different jobs. Let us know about how far it had come.
Our engineers do all of the cleaning where the vehicle has stopped, and once the engine has been run there is more of it. Caught early, it very seldom leaves long-term damage.
What does an AdBlue drain on a diesel involve around Mumbles Hill?
The vehicle stays where it is, whether that's a street near The Big Apple, a driveway, a layby or a filling station around Mumbles Hill, and the van travels to it. Three replies decide the work, so before anything else our technicians ask what was put in, roughly what quantity, plus if the engine has turned over.
On the spot, that tank is then emptied, and both the contaminated diesel and the urea leave at once. Residue from AdBlue will not wash away unaided, and so the fuel system gets a full flush, which matters much more with urea than for petrol. Clean diesel goes in after the filter is flushed — or swapped, when it needs to be — and after that your vehicle is tested. Roughly half an hour on site is usual for most jobs when the engine has not run. Explosion-proof pumps mean a live forecourt sensible to work on, and they're quiet enough not to disturb the street at night.
Clean diesel goes in to bleed your system, and that's the final step. After that our technicians start it and you head off, whether from a parking bay at Swansea or a drive around Mumbles Hill. Before we go, we make sure it is running smoothly with new diesel in. As the job is done in its entirety where the vehicle is, a workshop never comes into it. You get a VAT invoice and an engineer report later on, which is what insurers ask for.

AdBlue in a diesel tank around Mumbles Hill: the cost of fixing it
No single figure would be honest, since every job is different.
